An actuator with switchable releasing speed includes an actuation rod, a screw, and a motor. The motor drives the screw rotating so that the actuation rod axially moves relative to the screw. The motor includes a stator, a rotor, a plurality of commutators, and at least three brushes. The at least three brushes have a positive brush, a negative brush, and at least one auxiliary brush. The positive brush is connected to a positive DC voltage. One of the negative brush and the least one auxiliary brush is adjusted to connect to a negative DC voltage so as to change a rotational speed of the rotor, thereby controlling a movement speed of the actuation rod. Accordingly, the releasing speed of the actuator is switchable.

A brush ring assembly including a brush ring, a brush holder coupled to the brush ring, and a brush spring. The brush spring includes a coiled spring body, a first end portion and a second end portion. The first end portion and the second end portion are disposed on opposing ends of the spring body. The first end portion, the second end portion, and the coiled spring body are coupled to the brush holder. The first end portion is bent across at least a portion of the coiled spring body in a direction toward the second end portion.

Embodiments of the invention provide a pump comprising a lower housing, a diaphragm assembly, an upper housing, a valve housing, and an o-ring. The diaphragm assembly is positioned adjacent to the lower housing. The upper housing is positioned adjacent to the diaphragm assembly and includes an inlet chamber and an outlet chamber separated by a ring. The valve housing is positioned between the upper housing and the diaphragm assembly, encloses the inlet chamber and the outlet chamber, and includes a cutout in contact with the ring. The ring includes raised outer walls to receive the cutout and the o-ring is positioned between the raised outer walls of the ring and secured between the raised outer walls by the cutout.

A drive system with a plurality of electromotive drives, specifically servo drives, the electronics of which are interconnected or connectable by way of a hybrid bridge. The hybrid bridge has a hybrid cable and a plug-in connector on the cable termination side for power conduction and data transmission. There is provided a drive of this type and a hybrid bridge of this type.

Electrical machine (10), and also method for producing an electrical machine, in particular for adjusting moving parts in a motor vehicle by motor, having a stator (12) into which a rotor (14) can be inserted, wherein the stator (12) has two permanent magnets (18) which are situated opposite one another and which are arranged in a pole housing (16) which forms a magnetic return path, and the pole housing (16) has flattened regions (20) between the two permanent magnets (18), the pole housing wall (26) forming two magnetic follower poles (22), which are situated opposite one another, on the said flattened regions, wherein the maximum dimension (25) of the pole housing (16) between the two flattened regions (20) which are situated opposite one anotheraxially in the region of the follower poles (22)forms a width (24) across flats for the installation space of the electrical machine (10) which is equal to a maximum of 35 mmand in particular a maximum of 30 mm.

A motor transmission connection arrangement, in particular for use in vehicles, can comprise a motor pot, a brush holder, and a transmission housing. The motor pot, the brush holder and the transmission housing are pluggable to connect with one another, and the motor pot can include a number of centering surfaces, whereby the motor pot with respectively one of the centering surfaces comes into contact both with the brush holder as well as with the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another. The brush holder and the transmission housing can be concentrically oriented to the motor pot. In addition, the present disclosure refers to a sunroof for a vehicle with a motor transmission connection arrangement of this type as well as a vehicle with such a motor transmission connection arrangement.

Methods and systems are provided for a winch including a motor and a contactor assembly coupled around the motor. In one example, the contactor assembly is coupled around and in face-sharing contact with a portion of an outer surface of the motor. Additionally, the contactor assembly may include two or more coils spaced apart from one another within the contactor assembly.

A fluid delivery module includes a housing with a housing interior volume, the housing defining a first brush compartment and a second brush compartment within the housing interior volume; an inlet which introduces fluid into the housing interior volume; an outlet which discharges fluid from the housing interior volume; a fluid pump within the housing interior volume and having a pump section and a motor assembly which receives electric power through a first carbon brush and a second carbon brush such that the first carbon brush is received within a first carbon brush holder of the motor assembly and the second carbon brush is received within a second carbon brush holder of the motor assembly; and a filter within the housing interior volume which circumferentially surrounds the fluid pump. The first brush compartment encloses the first carbon brush holder and the second brush compartment encloses the second carbon brush holder.

A positive connection plate of a DC motor includes a fitting groove to enable assembling a specific brush holder thereto. The specific brush holder includes a convex part that fits in the fitting groove and a stepped surface having a step at a radially outer side of the convex part, and located at the opposite-core side of its armature from a core-side end surface of the convex part. A space existing in an axial stepped area which is located at the core side from the stepped surface and in which the step is formed is a stepped space. A drawing member is drawn from a position which circumferentially overlaps with the specific brush holder to the outside of a motor case, and is disposed so as to overlap with the stepped space in the axial direction.

Methods and systems are provided for a winch including a motor and a contactor assembly positioned within a same housing. In one example, the contactor assembly is positioned at an end of an armature of the motor and may include a controller configured to control winch component operation. The contactor assembly is electrically coupled to the armature via a plurality of electrically conductive brushes.
